I know that there are several posts on the same idea, and I have read most of them, but still, my questions persist. I have listed the other posts on the topic at the end of this post. All the other posts say that the electric field inside an ideal wire must be zero because:
- As the potential drop across the wire is zero, the electric field must be zero.
- Since "J = σ E", and for an ideal wire the σ tends to infinity, so E must tend to zero.
I understand these two arguments, but still, I have the following questions.
Consider a simple circuit with a battery and a resistance. And, the two are connected with ideal wires.
The following are the questions related to it:
If the electric field inside the ideal wires has to be zero, then how the current can flow in the circuit? Please explain to me with microscopic details, on how exactly the current flows in such a circuit and how exactly the electric field becomes zero inside the ideal wires.
Is it the intrinsic property of a current-carrying ideal conductor itself that the electric field through it should be zero, or it manages to get electric field inside to be zero in all the scenarios? If an ideal conductor manages to get electric field inside it to be zero, in all the scenarios, then how exactly it does that?
I am expecting an explanation which can fit in the imagination as well. A more intuitive explanation.
